- Use two different colors to depict the unduplicated chromosomes of species C with larger chromosomes (2n = 8) and species D with slightly smaller chromosomes (2n =10), and of their F1 hybrid. Is the hybrid likely to befertile?When species arise as a result of changes in chromosome number that make them incompatible with the parental species, it is referred to asExplain about Interspecific hybridisation.
- Why are interspecies hybrids usually sterile? How can the sterility of interspecies hybrids be overcome? How does the “triangle of U” illustrate this principle?(d) Scientists believe that the yellow fern arose from hybridization with another fern on the island. Create a diagram of this hybridization that tracks the origin of the chromosome number in the yellow fern.draw a punnett square, one parents is domincat tall, one is mixed hybrid, name 4 possible offspring.
- There are two genetic loci determiningthe mating type, locus A with 288 alleles and locus B with 81 alleles.(2 points) List a cross of two Schizophyllum commune strains that could successfully mate and across that could not succeed.Successful cross:Unsuccessful crossDefine hybridsn the savannahs of the Amazon different species of the genus Ipomoea are pollinated by either bumblebees or hummingbirds; lavender flowered I. marabaensis and red flowered I. cavalcantei. Which of the follwing data would support the suggestion of natural interspecific hybridization with weak postzygotic isolation? A. magenta flowered hybrids found in the wild were infertile and bidirectionally crossing with parental species B. magenta flowered hybrids found in the wild were preferentially pollinated by introduced honeybees rather than parental pollinators C. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis showed a mixture of parental floral characteristics D. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis and magenta flowered hybrid plants were autotropic and showed hybrid viability
